METHOD FOR STRIPPING OFF RESIN LAYER OF RESIN COATED METAL TUBE

摘要

PROBLEM TO BE SOLVED: To provide a method for stripping off a resin layer of a resin coated metal tube by which a resin layer can be easily and promptly stripped off by a peeling roll without reducing a diameter of a metal tube with respect to a resin coated metal tube having a resin layer (a resin coated layer) with a high adhesive strength and a thin wall, in particular.

SOLUTION: When the resin layer is peeled off and removed from the resin coated metal tube formed by coating the resin layer on the outer peripheral surface of the metal tube, the resin layer is peeled off and removed by relatively moving the metal pipe and the peeling roll in the peripheral direction while pressing the resin layer by a peeling roll for pressing radially inwardly from the outside, wherein the resin layer is peeled off and removed with the core inserted into the resin coated metal tube on the side in which the resin layer is peeled off and removed.
